Springfield Armory now sells the Kuna, a 9 mm compact firearm that uses roller delay, with a factory three-lug interface so matching silencers lock on and come off by hand through a press-and-rotate motion. The upper is a single aluminum piece, every control works from either side, and each gun ships with two 30-round magazines.

Customers can pick a model that leaves a bare Picatinny section at the rear or one that already carries a side-folding Strike Industries FSA brace. Both three-lug versions also come in 10-round form for jurisdictions that limit magazine size. Qualified professionals can buy through the company’s FIRSTLINE discount program.
